CMU CL: CMU Common Lisp

CMU Common Lisp (CMU CL) is a high quality public domain Lisp system.
It includes an incremental compiler, Hemlock emacs-style editor,
source-code level debugger, code profiler and is mostly X3J13
compatible, including the new loop macro.
The new CMU CL compiler (Python) is more sophisticated than other
Common Lisp compilers. It both produces better code and is easier to
use. Python does many optimizations that are absent or less general in
other Common Lisp compilers, and is particularly good at number
crunching.
See SUPPORT for important information regarding the support status of
CMU CL. (In short, the CMU CL project is no longer funded by Arpa,
so future support will be minimal. They'll fix bugs, especially
those that affect the use of CMU CL as a cross-development vehicle
for their Dylan work, but they won't be adding any major new features.
Continuing the same level of support is not an option without ARPA
or industrial financial support.)

[128.2.206.173]
The binary releases are contained in files of the form
-_.tar.Z
-extra-_.tar.Z
The first file holds binaries and documentation for the
basic Lisp system, while the second -extra file contains
the Hemlock editor, the Motif toolkit, the graphical
debugger, and the CLX interface to X11. Files of the form
-source.tar.Z
are of possible interest since they contain all the ".lisp"
source files used to build that version.
